The paint protective film and vehicle surface temperature should be 13-32°C (55-90°F) for best results. Automatic car washes should be avoided for at least 24 hours after the paint protective film application. You can wipe the vehicle surface with isopropyl alcohol or flash naptha at the application area, dry the surface with a clean lint-free cloth, create a mixture of 25 percent isopropyl alcohol and 75 percent water and two drops of baby shampoo per 16 oz of the fluid mixture, remove the backing liner from the protective film patch, use the solution to liberally spray the adhesive side of the protective patch, the mounting location along with your hands, position the paint protective film patch to the desired location on the vehicle, spray the surface of the film with the alcohol, water, and soap solution, start at the center of the protective patch, working outward to remove the air and solution from under the protective patch, release any air bubbles with a pin, dry the surface with a clean, lint-free cotton cloth.
